I had the chance to check out the before mentioned Norwegian Rain Moscow coat, it's really well made, BUT and it's a big but Kim K big, it doesn't have a zipper, which was a complete deal breaker for me, why or who would buy a -25 C winter coat without a zipper.

? I don't understand. It has buttons. Many of my big heavy winter coats have button fronts. Is there a reason why a zipper is necessary?
